To all 'whom it may cohcern':4

Be it known that I, EDMUND W. GiLLMAN, of Long Island City, in the County of Queens and State of NewYork, have invented an Inn` provement in Machines for Finishing Barrels, of which the following is a specification:

My invention consists of the combinations and arrangements of apparatus, hereinafter described, for evening the staves, pressing on To begin with, the barrel A, having the trussi, Yhoops `B B and C, is rolled into position on the rods D, and between 4the presser-ringsor collars E, which at the time rest on the rods D lbetween the headsE ot' the pushers G and G. (The pushers G, which are connected to the movable head H, are then pushed forward by the toothed bar I and wheel J, so as to press the ends of the4 stavesstrongly'- between the rings E," to even the staves lengthwise, or

the pushersfmay' be madeto act directly on the ends of the staves for this purpose before the rings jare brought down, their principal use beingy to gage the cutter for turningthe ends of the staves.: The pressure-rings E'are then swung over out of the way and the pushers are opened and adjusted on the barrel against the inner trusshoops G, and the heads Y K against the other hoops Pressure is again applied by the toothed rack and wheel, but this time against the hoops, for pressing themen and tightening up the joints ot' the staves. In order to` continuel pressing the hoop C further on after the others have been pushedV as far as iheycan be, it is made wider than the others, so that,by opening the pressers a little, heads K will pass over hoops B, while heads F still bear against hoops C. In the same manner the inner hoops B may be continued after outerV hoops B are'pushed as far as they go. The pushers are opened in this way by the cam-wheels M, which are turned by the shaft N, cranks O and P, and lever Q.

As -soon as the staves are pressed endwise and evened bythe rings E, they are dressed oft true bya rotary cutter (not shown) on the cutter-head V, running on the slowly-revolving carrying-head S of shaft T, said head V being turned by pulleys and a'belt or gears, W

4on the carrienhead, runs against the ends of the staves'to gage the distance of the evening, crozing, and chamfering toolsv from the ends of the staves, said tools being also carried bythe rotary cutter-head V, and one of which, say the crozingtool, is represented by a. This cutter-head V is Iitted -in bearings b,

which slide out and in on the carrier-head S, as requiied, for entering the end of the barrel, cutting the croze, and then withdrawing again, and the cam. d, shaft e, and crank f are proy vided for so working it. In order to prevent the tools of head V from cutting too deep in case the barrel is a little hat at one or more points, a strong pressure-gage, g, is mounted on the bearing of cutter-head V, to run around the barrel with the cutter-head and spring the cutters in and gage them to such flat places.

The shaft T is arranged to slide lengthwise in its bearings, to present the cutter-heads to the barrel properly,an d it is provided with a spring, p, to push it along when the pushers Gr are moved up to their work. The shaft T ismturned by suitable means connected with it by wheel i. The pressure-rings E and the pusherlheads F and K are made double, with A rubber cushions or springs j between the two.

parts, to be more easy on the machine than solid metal contrivances would be. In practice the shaft m ofthe arms which carry the rings E will be made in two yindependent parts,to

allow the rings to be moved toward and from each other, as required in evening the staves at the ends, and a spring, n, will be employed to push them apart to admit `the barrels. The pushers will, in practice, be contrived in segments of a circle, so that they will close together on and support each other in the right position for pressing the ends of the staves at the beginning of the operation.

They have springs q for closing them.

The machine is alike at both ends, except as to the endwiseA movements of the pushers.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The combination of the pressure-rings E,

with the pushers G, substantially as specified.

2. The bilge truss-hoops G and hoops B, in combination with pushers G andG, provided with pusher-heads F K, substantially as specified.

3. The pressure-gage g, in combination with cutter-head V and carrier-head S, substantially as specified.

4. The combination of sliding hollow shaft T, cutter carrier-head S, shaft Y, Wheels W X, and rotary cutter-head V, substantially as specified.

5. The combination of an interposed rubber spring, j, with the two metal parts composing the pusher-heads and pressure-rings, as and for the purpose set forth.
